I just purchased a Burton Nug Flying V Restricted 146, Medium Cartel Restricted EST bindings, and size 10 burton boots. My height is 5'7 and I weigh in at 125lbs. I know that the nug rides 8-10cm bigger and this is the first snowboard I've bought, so I just wanted to know if it would be alright for me. Im still a beginner as well. I just wanted to know if I should stick with my 146 or exhange it for a 142? Please give me some input!
